The world's most dangerous walks

There are walking holidays... and then there are extreme walking holidays. These death-defying hikes will make even the bravest of trekkers' stomachs drop.

While we're not encouraging you add these dangerous walks to your travel bucket list, you should definitely take a look at some of these pictures and videos taken by extreme travellers.

Thrill-seekers looking for the ultimate adrenaline rush on holiday have climbed the steepest mountains, crossed the most unstable bridges and trekked treacherous forests.

El Caminito del Rey in Spain (pictured), a walkway pinned along the steep walls of a narrow gorge near Malaga, was named the most 'dangerous walkway in the world' and has caused the deaths of several people.

Morecambe Bay, near the Lake District, is no place for a coastal walk either - it is one of the world's most dangerous beaches, due to its deadly sands and fast-moving incoming tides.

In Papua New Guinea, Kokoda Trail hikers face malaria, extreme heat and daily rain, as well as slippery routes and ankle-deep mud. Meanwhile, Switzerland is home to something completely different: the 'world's scariest bridge,' located 1,500ft above a glacier. Titlis Cliff Walk takes you over Europe's highest suspension bridge on a frightening walk and allows tourists to experience the surrounding mountains, see parts of Italy and peek down hundreds of feet into the abyss.
